Accounts Payable Audit
Recover hidden savings from your Accounts Payable processes
In busy finance departments, duplicate payments, overpayments, and supplier credits can go unnoticed and unclaimed.
With internal teams focused on day-to-day activities, our Accounts Payable Audit uncovers and recovers funds by reviewing supplier statements and historic transactions at scale.
Why do duplicate payments and supplier credits go unrecovered?
Even robust finance processes can lapse across thousands of transactions and suppliers. Over time, this leaves your money outside your organisation. Recovering these funds will immediately improve your cash flow and financial performance.
The most common challenges we see include:
- High supplier volumes and invoice numbers
- Limited time for supplier statement reconciliation
- Multiple sites, systems or teams creating fragmented processes
- Unallocated cash, credits and rebates are unnoticed in supplier accounts
- Manual recovery work adds extra pressure on the Accounts Payable teams

Accounts Payable Audit
Find and recover missing funds quickly
Our Accounts Payable Audit identifies and recovers duplicate payments and unclaimed credits from your suppliers. The Audit is a fully managed, secure, compliant, gainshare-based service. We require minimal resources from your in-house teams, and you don’t need to change your processes or invest in new software.
The Accounts Payable Audit consists of two component parts, Duplicate Payment Recovery and Unclaimed Supplier Credit Recovery, which can be run together or as a standalone service.
Duplicate Payment Recovery
Duplicate Payment Recovery identifies and recovers unintentional duplicate invoices and overpayments made to suppliers.
We use expert human analysts, sophisticated data analytics software algorithms, and AI to find duplicate payments within your historic payment data. We then contact suppliers on your behalf to recover the lost funds.
Our experts provide root-cause analysis to uncover why errors occurred. We offer practical recommendations to mitigate process gaps, strengthen controls and governance to reduce the risk of future duplications.


Unclaimed Supplier Credit Recovery
Our specialists identify and recover unclaimed supplier credits, unallocated cash, and missing rebates without increasing pressure on your internal teams.
Unclaimed credits can occur in the most robust financial environments, and managing thousands of suppliers and invoices can strain internal resources.
Using advanced automation and reconciliation software, our team analyse supplier statements to identify and recover credits and reinforce your financial controls.
